Abstract: The control and sanitation of water it’s a worldwide concerning problem. In particular is in developing countries where the need is more evident due to the lack of sources and appropriate structures to cope with the outbreaks of waterborne diseases. In most of cases, the cause of these significant epidemiological events have microbial origin. Despite of it the situation of water supplies and sanitation has improve all over the world in the last decades. Nanowire technology has already shown their ability to perform very effective and fast monitoring microbiological spoilage and quality control. The aim of this study was to test the ability of a novel S3 (Small Sensor System) nanowire device for the detection of complex mixtures of bacteria in potable water in order to approach into a real condition, in cooperation with GC-MS-SPME technique. The achieved results notably advocate the use of EN as a very easy to use, fast and accurate tool in water quality control.
